- Manipulating the light characteristics with LEDs (light-emitting diodes) allows the regulation of various aspects of plant growth and development. The aim of the study was to investigate the effect of supplementary irradiation with LEDs emitting blue, red or far-red light on the growth, chlorophyll content, and photosynthetic activity of in vitro-derived plants of two strawberry cultivars with different photoperiod requirements, short-day cultivar ‘Elsanta’ and photoneutral cultivar ‘Selva’. Supplementary irradiation with blue light significantly affected the growth parameters of plants of the photoneutral strawberry ‘Selva’, but had no effect on the growth of ‘Elsanta’ plants. Exposure to blue light did not affect the chlorophyll content index (CCI) or the maximum efficiency of the photochemical reaction of photosystem II (Fv/Fm) of any strawberry cultivars. Red and far-red light supplementary irradiation did not significantly affect plant growth, but it improved the Fv/Fm parameter in both strawberry cultivars after 57 days of the experiment. Irradiation with red and far-red light inhibited the formation of runners, while blue light limited their development by 50%.
